Abstract

Cette invention concerne un réacteur de chocs fluidiques comprenant un concentrateur de résonances de choc et au moins un dispositif de collision de jets. Le dispositif de collision de jets est constitué de deux groupes d'éléments d'orifice d'injection disposés coaxialement en sens opposé, chaque élément comportant le même orifice d'injection (141). Le concentrateur de résonances de choc se présente sous la forme d'une boîtier renfermant une chambre concave sphérique rigide (2) ou autre combinaison de convergence à surfaces courbes rigides faisant converger le choc depuis un foyer de convergence de nouveau sur le foyer de convergence pour produire une onde de choc. Une goulotte de jet abritant l'orifice d'injection et une sortie de décharge (13) pour le fluide traité évacué hors du boîtier sont disposées sur ledit boîtier. Le point médian de la ligne entre les deux orifices d'injection (141) se situe au centre de la sphère de la partie concave (2) ou sur le point de convergence de la combinaison des surfaces courbes de convergence. La somme des sections en coupe de la sortie de décharge (13) est beaucoup plus importante que celle de tous les orifices d'injection (141). La surface en coupe et la position d'ouverture de la sortie de décharge (13) assure le remplissage complet du boîtier avec le fluide à traiter pendant la marche du réacteur de chocs fluidiques.
